Tk_GetVRootGeometry(3) Tk Library Procedures Tk_GetVRootGeometry(3)______________________________________________________________________________NAMETk_GetVRootGeometry - Get location and size of virtual root for window
SYNOPSIS
#include <tk.h>
Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)
ARGUMENTS
Tk_Window tkwin (in) Token for window whose virtual root
is to be queried.
int xPtr (out) Points to word in which to store x-
offset of virtual root.
int yPtr (out) Points to word in which to store y-
offset of virtual root.
int widthPtr (out) Points to word in which to store
width of virtual root.
int heightPtr (out) Points to word in which to store
height of virtual root.
_________________________________________________________________DESCRIPTIONTk_GetVRootGeometry returns geometry information about the virtual root
window associated with tkwin. The “associated” virtual root is the one
in which tkwin's nearest top-level ancestor (or tkwin itself if it is a
top-level window) has been reparented by the window manager. This win‐
dow is identified by a __SWM_ROOT or __WM_ROOT property placed on the
top-level window by the window manager. If tkwin is not associated
with a virtual root (e.g. because the window manager does not use vir‐
tual roots) then *xPtr and *yPtr will be set to 0 and *widthPtr and
*heightPtr will be set to the dimensions of the screen containing
tkwin.
